Committee on Seismology and Geodynamics


Project Scope:

The Committee on Seismology and Geodynamics (COSG) was formed in 2001 as a standing committee of the Board on Earth Sciences and Resources. This committee succeeded three former entities: the Committee on Seismology, the U.S. Geodynamics Committee, and the Committee on Geodesy.

COSG provides independent advice to all levels of government and society on scientific, technical, and policy matters related to seismology, geodesy, and geodynamics.

Members are drawn from the public, academic, and private sectors and have a broad range of expertise and experience. The mission of the committee is as follows:

  • To foster and encourage understanding of the structure, dynamics, and evolution of the Earth.
  • To review and define basic and applied research activities in seismology, geodesy and geodynamics that contribute to federal agency missions.
  • To address the transfer of seismological and geody­namics knowledge to areas of public welfare and national need including topics such as earthquake science; geological hazards; energy, mineral, and water resources; national security, global climate change; land-use planning; and public education.
  • To foster long-term national efforts to collect, store and openly disseminate seismological, geodetic, and geodynamical data of all types.
  • To foster long-term national efforts to monitor geodynamical events as well as nuclear testing treaties using geophysical technologies.
  • To serve as the U.S. member of the International Lithosphere Program.

His group uses seismic and GPS sensing networks and is experimenting with the use of smartphones. Testing of a warning system for the U.S. west coast is currently underway. Dr. Allen’s group also uses geophysical sensing networks to image the internal 3D structure of the Earth and constrain the driving forces responsible for earthquakes, volcanoes, and other deformation of the Earth’s surface. His research has been featured in Science, Nature, Scientific American, The New York Times, and dozens of other media outlets around the world. Dr. Allen has a B.A. from Cambridge University, a M.Sc. from the University of Durham, a Ph.D. from Princeton University, and was a Postdoctoral Fellow at the California Institute of Technology.
Mark D. Behn
MARK D. BEHN is a senior scientist in the Department of Geology and Geophysics at Woods Hole Oceanographic Institution (WHOI). Dr. Behn’s research investigates the dynamics of Earth deformation in glacial, marine, and terrestrial environments through the use of a wide range of geophysical techniques. These techniques include the development of geodynamic models that relate laboratory-based rheologic and petrologic models to the large-scale behavior of the Earth, which are then applied to a spectrum of problems from basic science to societally-relevant issues. His research interests include dynamics of faulting, magmatism, and surface processes at mid-ocean ridges and continental rifts; seismic anisotropy and imaging of sub-asthenospheric mantle flow; evolution of the continental crust; and ice-sheet dynamics. He is the co-chair of the Geodynamics Focus Research Group for the Community Surface Dynamics Modeling System, was active in the MARGINS/GeoPRISMS program, and is a former fellow of the WHOI Deep Ocean Exploration Institute. Dr. Behn received his B.S. in geology from Bates College and a Ph.D. in marine geophysics from the Massachusetts Institute of Technology/WHOI Joint Program.
Cynthia Ebinger
CYNTHIA (CINDY) EBINGER is a professor and Marshall-Heape Chair in the Department of Earth and Environmental Sciences at Tulane University. Her current research aims to understand the partitioning of strain between faulting and magmatic processes within continental and oceanic rift zones over time scales of hours to millennia and the longer-term evolution of continental rift zones from initiation to continental rupture. Her interest in continental rifts and plate boundary deformation began as an undergraduate at Duke University when she took part in a National Science Foundation-sponsored research project in the volcanically and seismically active East African rift zone. Dr. Ebinger served as a former president of the Tectonophysics Section of the American Geophysical Union (AGU) and was recently named an AGU Fellow for her "fundamental work on the evolution of continental rifts toward seafloor spreading in East Africa and afar." Dr. Ebinger earned her B.S. in geology from Duke University, S.M. from Massachusetts Institute of Technology (MIT), and Ph.D. in oceanography from the MIT/Woods Hole Oceanographic Institution (WHOI) Joint Program.
Steven D. Jacobsen
STEVEN (STEVE) JACOBSEN is Professor of Earth and Planetary Sciences at Northwestern University and a geophysicist specializing in mineral physics. He studies the role of volatiles, especially water, in controlling geophysical processes driving the evolution of Earth’s crust, mantle, and atmosphere. He developed an ultrasonic technique for the diamond-anvil cell, which measures acoustic velocities in Earth and planetary materials at mantle conditions. By examining the influence of water on material properties and melt generation, Dr. Jacobsen is working to map mantle water content from dense regional seismic data such as the USArray. His research has broader implications for the global geochemical budget and origin of Earth’s water. Dr. Jacobsen is active in science and development at large-scale user facilities for highpressure synchrotron research including the Advanced Photon Source at Argonne National Lab and the National Synchrotron Light Source-II at Brookhaven. His awards include a Presidential Early Career Award for Science and Engineering and a David and Lucile Packard Fellowship.

Description :   

Beyond the Black Box: The Future of Machine Learning and Data-Intensive Computing in the Solid Earth Geosciences

Monday, October 28, 2019
Washington, DC - Keck Center

The application of computational algorithms such as neural networks that underpin machine learning (ML) have grown within geophysics over the past several decades. In recent years, the increasing power of computing systems when combined with exponentially growing data holdings is leading to exciting new results and tremendous interest in ML and its application in the geophysical sciences. The solid Earth geosciences have large datasets and are developing the expertise to make major contributions to the ML discipline as a scientific discovery tool.  
 
This meeting reviews progress and future investments needed for a more concerted and long term effort to combine datasets with appropriate data-intensive computing resources. This is the natural laboratory necessary for data and geoscientists to most effectively work together, and COSG will discuss how those workflows can be combined with approaches that provide insights into the physics of earth systems, beyond black-box applications.

Description :   

(RE)ASSESSING SEISMIC HAZARD ACROSS THE UNITED STATES
Seismic events pose a serious risk to life and infrastructure across the U.S. Yet these events are rare, making the historic
record incomplete and our understanding of their impacts limited. In addition, seismicity rates have been substantially
modified by human activities over the last decade adding an additional unknown to future hazards. COSG hopes to review
the state of knowledge, the uncertainties, and strategies to improve hazard estimates and will explore the approaches used
to estimate the hazard. COSG is interested in how recent advances in understanding of the earthquake processes, along with
the collection of new massive seismic datasets, might be used to improve assessments of the hazard.
